Applicationnled November 17, 1902. Renewed November 10, 1903. Serial No. 180,629. (No model.)

To all whom it may concern..- i

Be it known that I, ANTHONY HAAG, a citizen of the United States,residing at NewYork, in the county of New York and State of New York, have invented certainnew and useful Improvements in Build-ing Construction; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it` appertains to make and use the same.

My invention relates to certain new and useproof or cement floors; and it consists in a hanger for Supporting the temporary struc-v ture or form between the iron beams or girdeTS UPII Whichthe'concrete or cement'loor-y l 111g 1s to be laid. ,Y

` The object .of the invention is to provide a hanger of this character which is of simple and inexpensive construction, which will prevent the concrete or cementcomposition from shrinking away from the-iron beams, and by means of which the temporary arch structure or form may be quickly and easily placed in position to support the concrete or cement and then removed after the same has hardened.

With these and other objects in view the invention consists of certain features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure lis `a perspective View of my improved hanger or stirrup. Fig. 2 is a side elevation of the same applied to an I beam or girder commonly used in the construction ofl buildings. Fig. 3 is a sectional View through a portion of a concreteflooring, showing my hanger supporting the temporary structure upon which the concrete flooring is laid. Fig. 4. is a similar sectional view after the iiooring has hardened and the temporaryarch or supporting structure has been removed.

Referring more particularly to the drawings, the numeral l denotes my improved hanger or clip, consisting of'a single piece of metal or a metallic rod, preferably steel, bent as shown in the drawings. The horizontal end portions 2 and 3 are adapted to lie upon the top and bottom flanges oi' the metallic I- ing construction.

. beam 4., whichis very generally used in build- The ends of these horizons `tal portions are bent, as shown at 5, to engagefthe flanges of the beams or girders. `tical portion 6 extends parallel with the web` "of the beam from the upper horizontal por'- `tion 2 to the lower flange of the beam, wherev Lit meets-the lower horizontal portion 3, and :fromthis point the two portions extend up- .wardly at an angle and parallel to form the .hook-like portion 7. f f

As will be seen upon reference to Fig. 3 of the-drawings, when it is desired to lay a oonfcrete or cementv flooring the lhangers are The verplaced `at proper `intervals along the parallel Ibeamsor girders 4.0i' the floor with the hooked ends 5 engaging the upper and lowerl l'anges of the beams. In this position the hook portions 7 extend inwardly to support the haunch-boards 8. TheV trusses 9, upon 'which the temporary looring 10 of the arch rests, .are supported between the haunchsaid irons or hooks are fastened to the ends of the trusses 9 and are adapted to hook over or engage the top edges ofthe haunch-boards. When the temporary structure or form is thus arranged, the concrete or cement composition '12 is laid upon the same Ybetween the girders, as shown in Fig. 3. After the concrete or cement flooring has hardened the temporary form or structure isremoved by cutting off the hook portion at its lower end, as shown Vin Fig. 4. When this is done, the hook portions 7 the horizontal portions 3, the haunchboards 8, the trusses 9,andl flooring 10 will drop, leaving the under side ofthe concrete flooring. a smooth and finished ceiling. The

"vertical portion 6 and the upper horizontal portion 2 remain embedded in the tlooring.

It will be observed that the vertical portion .boards by the stirrup irons orhooks 1l.- The 6 and upper horizontal portion 2 sustain the best part of the weight andthe lowerv horizontal portion 3 and its hooked endf hold the haunch-boards closely to the flanges of the I-beams and prevent sagging. It will be further noted that the trusses 9 strengthen the hook portions 7 and the haunch-boards 8 and support them in the proper position.

By means of -my invention vthe temporary IOO supporting structure or form may be-easily and quickly erected with very little labor, and the trouble and expense of nailing up a new structure each time is obviated.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation, and advantages of my improved building construction will be readily apparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be' resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A clip or hanger for the purpose described, comprising end portions provided each at one end with a hook to engage the flanges of a beam kor. girder and'connected solely at their opposite ends, substantially as described.

2. A clip or hanger for the purpose described, comprising end portions, each having an engaging hook at one end, and a connecting portion between the other ends, and provided with an oifstanding supporting-hook, substantially as described.

3. In a device of the character described, the combination with beams or girders and a temporary supporting structure or form, of a c lip or hanger provided with portions adapted to engage the top and bottom ianges oi' the beams and with a doubled hook portion for supporting the temporary structure or form, said hook portions being adapted to be severed to permit of the removal of the temporary structure or form, substantially as described.

4. 1n a device of the character described, the combination with beams or girdcrs and a temporary supporting structure or form, of clips or hangers formed ot' a continuous piece of metal and provided with horizontal portions having hookcd ends for engaging the flanges of the beam, with a doubled, severablc hook portion for supporting the structure or form and with a vertical portion connecting the upper horizontal portion and the hook portion, substantially as described.

5. The combination with beams or girdcrs and clips or hangers having severable hooks, of haunch-boards adapted to be supported by said hooks, trusses provided with stirrup irons or hooks adapted to engage the upper edges of the haunch -boards for supporting said trusses and a temporary flooring upon said trusses, substantially as described.

6. A clip or hanger for the purpose described, comprising portions to engage the top and bottom flanges of a beam, a vertical connecting portion, and an ofstanding hook serving as a connection between said connecting portion and the portion for engaging the bottom flange of the beam, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ANTHONY HAAG.
